Combining the properties of organic and inorganic components with high surface areas and large pore volumes opens up countless possibilities for designing materials tailored to a wide range of advanced applications. As the majority of mesoporous hybrid materials are siliceous, the development of cost-effective synthetic approaches to produce water-stable hybrids with controlled porosity and functionality remains essential. Herein, we describe an original strategy for the synthesis of bridged mesoporous titania-bisphosphonate hybrids based on a one-step, template-free, non-hydrolytic sol-gel process. The reaction between Ti(OiPr) and several flexible or rigid bisphosphonate esters, in the presence of acetic anhydride (AcO) leads to the formation of TiO anatase nanorods interconnected by fully condensed bisphosphonate groups. The general method that we depict is quantitative and low cost. All materials are mesoporous with very high specific surface areas (up to 520 m·g⁻) and pore volumes (up to 0.93 cm·g⁻).
将具有高比表面积和大孔体积的有机和无机组分的特性相结合，为设计适用于广泛先进应用的材料开辟了无数可能性。由于大多数介孔杂化材料是硅质的，开发具有成本效益的合成方法以生产具有可控孔隙率和功能的水稳定杂化材料仍然至关重要。在此，我们描述了一种基于一步、无模板、非水解溶胶 - 凝胶过程合成桥连介孔二氧化钛 - 双膦酸酯杂化材料的原创策略。在乙酸酐（AcO）存在下，Ti(OiPr)与几种柔性或刚性双膦酸酯之间的反应导致形成由完全缩合的双膦酸酯基团互连的TiO锐钛矿纳米棒。我们所描述的通用方法是定量且低成本的。所有材料都是介孔的，具有非常高的比表面积（高达520 m·g⁻）和孔体积（高达0.93 cm·g⁻）。
